FLOUR SIF'IER.

Application filed November 6, 1925. Serial No. 6?,335.

This invention relates to new and useful improvements in sitters, andparticularly to flour sitters.

One object of the invention is to provide a device of this characterwhich is simple in construction, durable and effective in use, and whichcan be manufactured at a comparatively low cost.

Another object is to provide a sitter having an agitator therewithin,constructed and arranged so that the said agitator may be easilymanipulated by the thumb of the hand which grasps the handle ofthe'device.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure l is a vertical sectional view through a sifting device made inaccordance with the present invention.

Figure :2 is a vertical sectional view taken in a plane at right anglesto that of Figure 1.

Referring particularly to the accompanying drawing, 10 represents themetal shell of the sitter, which has the ordinary loop handle 11 securedto one side thereof. cured in the lower end of the shell 10 is theconcavo-convex sifting screen 12. Disposed transversely through theupper portion of the shell, and extending from a point adjacent thehandle 11, is a shaft 13, the opposite ends of which are fixed in thewalls of the shell. In the end of the shaft, adjacent the handle 11,there is formed an enlargement 14. A wire yoke 15 has one end formedwith an eye 16 which receives one end of the shaft 13 therethrough,within the shell, and a second eye 17 which is engaged on the other endof the shaft, between the enlargement 14 and the adjacent side of theshell. This lastnamed end of the yoke is continued upwardly above theupper end of the shell, and thence outwardly thereof, where it is formedwith a fingerpiece 18, arranged in position to be engaged by the thumbof the hand which grasps the handle 11, whereby the yoke may be rocked,and the main portion thereof caused to scrape on the concave part formedwith the coil turns 20, which are engaged on theshaft 13 between the eye17 and the adjacent side of the shell 10. One end of the spring 19 isformed with a hook 21 which is engaged with the arm of the yoke 15,above the eye 17, and the other end anchored in the shell at a suitabledistance from'the other side of the adjacent end of the shaft 13. Thenormal tendency of the spring is to expand and force the adjacent end ofthe arm of the yoke away from the shaft whereby to cause the yoke toslide toward the opposite side of the screen. The operator presses thefingerpiece' 18 in the op posite direction, against the tension of hespring, whereby to rock the yoke in the op posite direction, and uponreleasing pressure on the fingerpiece, the spring will return the yoketo normal position. Thus, by pressing the fingerpiece and releasing thesame, the

yoke may be moved backwardly and forwardly across the screen, with theresult that the operator can hold the sifter, and manipulate theagitator with one hand.

What is claimed is:

A flour Sifter comprising a shell, a sifting screen in one end of theshell, a transverse shaft extending through the opposite sides of theshell'and having a loop adjacent one end, within the shell, a wire yokein the shell with its hight portion contacting with the screen, one ofthe arms of the yoke having a terminal eye receiving the shafttherethrough, the other arm of the yoke having an intermediate eyereceiving the shaft therethrough, said other arm being extended abovethe shell to form a hand grip, said loop preventing movement of said.eye on the shaft inwardly of the shell, and a spring having itsintermediate portion coiled about the shaft between the loop and shellwall and having one end anchored in the shell wall and the other engagedwith the hand-grip.

In testimony whereof, I ail-ix my signature.
